Morbidly obese and skin care

Thanks all. I really don't think it's yeast. But there is an odor. The crack of the fold gets really red, then sometimes bleeds. She has had a blister pop up and took a week then it went away with antibiotic and dressing. The other things look like skin tears on the inner fold. It is so big and tight that I have to have an aide hold it up for me just to get in there and look. Maybe I will try the fungal powder. It just doesn't have the look of yeast. Yes she is pretty dependant on us. We have to use the lift to get her to the bathroom, and into her WC. She has her mind more of less, so it is hard to get her to eat right as she sure likes the PBJ sandwiches everyday. I also have put in for the bigger bed. Hopefully she gets it. Thanks folks and keep the suggestions coming. This lady is very special. And it sure is early so excuse my writing. Thanks.
